Continuous concrete bridge structure
Zemánek, Tomáš ; Lerch, David (referee) ; Koláček, Jan (advisor)
The diploma thesis is focused on solving road bridge situated between Roudno and Razová village over the water basin Slezská Harta. Before the design itself 3 studies were created and compared together. The selected variant is a continuous box girder with inclined walls, post-tensioned by bonded cables. The girder of a total lenght 148,0 m and width 13,6 m is divided into three spans. Height of the girder is 3,3 m. A detailed structural design, including construction limit state assessment, prestress design and time dependent analysis verification is processed. The design and the assessments of temporary and permanent situations are made according to valid standarts and regulations. Drawings and vizualizations are parts of the diploma thesis.

Multi-span bridge structure
Necid, Miloš ; Brtáň, Stanislav (referee) ; Koláček, Jan (advisor)
I deal with the road bridge near Velké Meziříčí in the thesis. The highway bridge overcomes valley 360 m long and 36 m high. For each course there is a separate super-structure. Each of the support structures converts three stripes of road transport. I do calculation of internal forces both manually and in Scia Engineer. In the thesis is drawings, showing the gradual construction, diagram of prestressing and reinforcement.

Footbridge across the Labe
Krč, Rostislav ; Romportl, Tomáš (referee) ; Stráský, Jiří (advisor)
The thesis focuses on design of prestressed concrete footbridge which passes pedestrian and bicycle path over the Elbe river near city of Celakovice in the Czech Republic. Three different bridge options were analyzed and for further development a cable-stayed footbridge was chosen. Its bridge deck is formed of a box girder supported by cables in its vertical axis and all cable stays are anchored into two concrete A-shaped pylons. This structure was analyzed in SCIA Engineer and assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Both the global structural behavior and the local structural integrity of box cross-section were assessed as well as construction stages and cross-sections of pylons and cable stays. Assessments were performed in IDEA StatiCa combined with hand calculations. Eventually a dynamic response of structure was analyzed. Natural modes and frequencies were found and forced oscillation response was evaluated. The thesis includes technical drawings, construction process and visualization.

Highway bridge over wide wally
Mertová, Eliška ; Smejkal, Ing David (referee) ; Klusáček, Ladislav (advisor)
The aim of this diploma thesis was the design of three possible variants, how to span the wide and deep valley with a bridge. After an evaluation, situation of the highway on the only wide load-bearing structure which is constituted by a box girder with transverse cantilevers supported by prefabricated bar braces, was chosen as an optimal solving. The load- bearing structure made of post- tensioned concrete is going to be incrementally launched and be supported by one-column pillars along an axis of the motorway. The work is composed of a detailed design of this preferred variant, which is processed according to the ultimate and serviceability limit state including the construction stage analysis of the bridge by the construction technology by an incremental launching method.

Bridge crane two-girder
Vajmar, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis describes the design of two-girder overhead crane. At the beginning of the work are designed sectional characteristics of the girder and the crossbeam. Furthermore, they are calculated loads applied during crane operation. Following the determination of the static load and fatigue strength. All calculations are solved with respect to relevant standards relating to overhead cranes. The work also includes analysis of purchased components, which are geared motors, bumpers and drive (no drive) wheels.

Double Box Girder Bridge Crane
Vlachovič, Tomáš ; Cupal, Vladimír (referee) ; Pokorný, Přemysl (advisor)
The diploma thesis deals with the assessment design of two-girder crane bridge for the lifting capacity 50 tons. Span of the crane is 20 meters, wheelbase is 3.15 meters and lifting height is 7 meters. This diploma thesis deals with the numerical solution box beam and using the finite element method is solved buckling. The diploma thesis has been elaborated using the relevant technical literature and standards that contain procedures and recommendations for calculation and designing of bridge cranes.

Prestressed bridge No. 202 on the expressway R2 in Slovakia
Janek, Tomáš ; Urban, Jiří (referee) ; Koláček, Jan (advisor)
My diploma thesis deals with design of the bridge number 202 on expressway in Slovakia. The bridge leads across the road number I50 (between Trenčín and Bánovce nad Bebravou) and railway number 130 (between Trenčín and Chynorany). For each course there is a separate super-structure. Only left super-structure is considered for the work. The box girder with four spans is chosen from three variations. This bridge is designed according to limit states, construction´s influence on design is taking into consideration. Structural model of construction is made as a spatial bar model. Structural analysis, well arranged drawings and visualization are elaborated in this thesis too.

Straddle Carrier
Wojnar, Tomasz ; Malášek, Jiří (referee) ; Pokorný, Přemysl (advisor)
This bachelor’s thesis focuses on a design of loadbearing frame and raising mechanism of straddle carrier, which is used in container terminals. It’s made for transport of container on the surface of terminal. It’s about designer calculation of individual parts of crane frames, applicability of designed parts is checked by strength calculation. Raising mechanism is designed with drive of stroke. Outputs of this bachelor’s thesis are drawings.

Design of doublebeam of bridge crane 50 tonne
Matěja, Josef ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
The Bachelor’s thesis deals with the design of two-girder crane bridge for the lifting capacity 50 tons. The process is split in eight parts. The first one contains a preliminary scheme of the whole design and proposal of main parameters. The second part contains calculation of preloading of the girder, specification of its main dimensions and calculation of maximum bending moment. The other parts include calculations and designing of individual main parts and accessories such as crane girder, cross girder, wheels, rails, gear and brake. The bachelor’s thesis has been elaborated using the relevant technical literature and standards that contain procedures and recommendations for calculation and designing of bridge cranes.
